Nearly Perfect Raman Self-Cleaning in Graded-Index Multimode Fibers Using Pearcey-Gaussian Pulses
IEEE Access, 2021 We propose a temporal manipulation scheme for the inner-mode interactions in graded-index multimode fibers (GRIN-MMF). In this scheme, a so-called Pearcey-Gaussian (PeG) wave packet is constructed for the pulse profile, which allows the manipulation of ...

Efficient modelling of nonlinear propagation in multimode graded-index fibers [PDF]
, 2018 International audienceWe develop an effective 1+1D model describing nonlinear propagation in multimode graded-index fibers. The model is able to quantitatively reproduce recently observed phenomena like geometric parametric instability and broadband ...

Depolarization of Light in Optical Fibers: Effects of Diffraction and Spin-Orbit Interaction
Fibers, 2021 Polarization is measured very often to study the interaction of light and matter, so the description of the polarization of light beams is of both practical and fundamental interest.

A systematic analysis of parametric instabilities in nonlinear parabolic multimode fibers
APL Photonics, 2019 We provide a systematic analysis of geometric parametric instabilities in nonlinear graded-index multimode fibers. Our approach implicitly accounts for self-focusing effects and considers dispersion processes to all orders. It is shown that the resulting
